Instagram client-auth missing #access_token after redirect

Question

A previously working Instagram client-authentication flow recently broke due to missing access token after redirection

• https://instagram.com/oauth/authorize/?client_id=MY_CLIENT_ID&redirect_uri=http://myapp.com/success&response_type=token&display=touch&scope=basic

Instagram properly redirects the user to myapp.com/success#access_token=some_token in Chrome.

However, when accessing the URL from within (iOS) client code / desktop Safari the redirect happens without any appended #access_token data

Answer 1

I had run into the same issue with instagram client-implicit auth on iOS app, I think it is the iOS webview not allowing hash fragment. Here is my question from the past: How to get hash fragment of URL from UIWebView

Answer 2

I had the same problem with my site http://slidetagram.com

This is an known issue on Safari.

To fix this you have to add an extra slash before the # on your page to be redirected.

In my case I've changed from

http://slidetagram.com/slide#access_token=...

to

http://slidetagram.com/slide/#access_token=...

After that change, it worked fine!
